I'm getting back to you on this as when I first reported it you seemed to suggest it may be because you had just moved your demo servers. So anyway I tried again and can tell you that in Windows with browsers other than Firefox, there is a crazy thing that clicking the items on the notifications bar seems to have no effect. I have found if I do lots of Ctrl - to zoom right out, I see clicking does work but it puts the text way way off screen! In the end as I was not able to see your product work because of this I ended up going with JomSocial so will see if I made a good choice, but anyway so you don't lose other sales you might want to fix this issue. I tried with IE and Safari and they both show this behaviour. (by the way, the screenshot shows clicking the rhs notification, I zoomed right out and still couldnt see the message when I used the top icon!)
